问题 I am having an issue with binding to a parent MainWindow property, MainContentVisibility. I have the following code: MainWindow.xaml <Window x:Class="CallTracker.WPF.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:v="clr-namespace:MyProgram.WPF.Views" DataContext="{Binding MainPageViewModel, Source={StaticResource Locator}}"> <StackPanel> <v:CompanyInfoUserControl Width="800" Visibility="{Binding MainContentVisibility, RelativeSource={RelativeSource Mode

Once you
